HugAgentOS

HugAgentOS is an enterprise-grade agent operating system that uses domain ontology to power trustworthy reasoning and task execution.

HugAgentOS is an open-source, self-hosted enterprise agent operating system designed to give AI models the context and tools needed to carry out real tasks. It treats domain ontology as a control plane for agent reasoning, decisions, and actions. The Community Edition combines agentic chat, private knowledge-base retrieval, sub-agents, MCP tools, agent skills, sandboxed execution, and long-term memory in a single workspace. It supports OpenAI-compatible or local models, connecting cloud or local options through model-service configurations. Users can deploy it via a one-command installer on Linux, macOS, and WSL2, or through Docker Compose using PostgreSQL and Redis. It is built for individuals and organizations seeking structured compliance, evidence-based review, and traceable agent evolution.
